COMMENTS FROM READERS

"In an age when many technical authors feel they must inundate their
readers with thousand page textbooks, it was a pleasure to read your
beautiful book. It succinctly gets to the important topics and helps
the reader separate the 'wheat from the chaff'. The illustrations
and typographical layout are great!"

- Ed Marvin, Senior Principal Engineer, The Boeing Company

"I found it a breath of fresh air with its patient and unpatronizing
approach to the world of signals and systems."

- Tomas Ward, Professor, Univ. College Dublin (Ireland)

"Accelerates the learning process by bringing out the key points on
each topic in a clear, easy-to-read manner. Guaranteed to be a real
time-saver for students."

- Deron Jackson, 6.003 Head Teaching Assistant, M.I.T.

"Packed with more information per page than any other book of its
kind. A valuable resource for any engineer."

- Jeff Levison, Engineer, Jet Propulsion Laboratory

"Finally I have found a book on Signals and Systems that is written in plain English."

- Jesse Manibusan, Student, U. Hawaii

"I was very impressed with the quality and scope of your book; it
is one of the best engineering textbooks I have purchased."

- Steven Marrano, Professional Engineer, American Water Works

"Really enjoyed your book. It helped me tie the concepts together after
a long period of using some and letting the others slip by the wayside."

- Dan Sternlicht, Researcher, Scripps Institution of Oceanography

"A worthwhile companion to traditional texts in the field."

- Dr. Andy B. Dobrzeniecki, Instructor, Harvard Medical School

"I can say this is the best book I have seen which summarizes a lot of
the fundamentals you really should know in a nice, clearly formatted,
condensed form."

- Brian Marquis, Graduate student, Mechanical E., Tufts Univ.

"Written with the student in mind in an unusually clear and simple
language. It's like having your own personal tutor. I wish I had
this book when I was studying for my qualifiers."

- Rachel Learned, Doctoral candidate, M.I.T.

"Clearly emphasizes relevant concepts and problem-solving skills
without losing the reader in unnecessary details. This is the kind of
book that should have been written long ago."

Comments by MIT students

The Underground Guide to
Course 6 is an unofficial, but highly utilized, course evaluation
guide for the Electrical Engineering and Computer Science courses at MIT.

Most students take these comments quite seriously and often base future
class decisions on them. The excerpts below are taken from the
synthesized summaries compiled from student evaluation forms given out
at the end of each term.

No textbook was required for the course, although many students mentioned
that they found Signals and Systems Made Ridiculously Simple highly
useful. (Spring '00)

Most students found Signals and Systems Made Ridiculously Simple
to be infinitely more valuable than either the Seibert text or the Oppenheim
text. (Fall '98)

Most students disliked the text by Siebert, but the
text by Oppenheim and Willsky was better. Many students thought that Signals and
Systems Made Ridiculously Simple was a great text and should be required for the
course. (Spring '98)

Most students found the required text by Siebert difficult to
understand. An optional book, Signals and Systems Made Ridiculously
Simple by Karu, was much more useful. The lecture notes were also
highly praised by students. (Fall '97)

6.003 has one required text, written by Siebert. Another by Oppenheim
and Willsky is recommended. Most students found these books difficult to
read and understand, and rarely used them. An optional book, Signals
and Systems made Ridiculously Simple by Karu, was simpler and was found
to be much more useful. These references were augmented by the lecture
notes, which were helpful to many students. (Spring '97)

The text by Siebert was widely viewed as poor. The second required
text, by Oppenheim & Willsky, was thought to be an adequate
reference. Students were annoyed at having to buy two expensive books,
neither of which were overly helpful. Signals and Systems Made
Ridiculously Simple, by Z. Karu, was highly praised. Most students used
the lecture notes and Karu's book instead of the texts. (Fall '96)

There were two textbooks for 6.003, one by Siebert and one by
Oppenheim. Most students disliked the textbooks and said that they were
only needed for the problems. Of the two, Oppenheim was more readable
and useful. Most students recommended getting the Signals and Systems
Made Ridiculously Simple guide. In fact, many students claimed to have
used only that and the lecture notes. The book by Siebert was considered
a deeper text and was difficult to appreciate on the first reading.
(Spring '96)

Siebert's text was widely considered unreadable and filled with
irrelevant examples. However, the class notes were clear and
well-written. Some found Karu's Signals and Systems Made Ridiculously
Simple to be very clear and helpful. (Fall '95)

The textbook was useful, but widely considered quite dry and boring.
It presented a large amount of material to digest. Most students
appreciated the supplemental text, Signals and Systems Made
Ridiculously Simple, for being very helpful on problem sets and test
preparation. (Spring '95)

Students generally agreed that the text, while thorough, was somewhat
advanced and difficult to understand. Some suggested relying
exclusively on the course notes, Signals and Systems Made
Ridiculously Simple. (Fall '94)

The textbook was Circuits, Signals, and Systems by Siebert. Many
found the book confusing because information was presented densely. One
student described it as "quite good but not always readable." The
handout 6.003 Made Ridiculously Simple was a good test
preparation. (Spring '94)

Head TA Z. Karu was universally praised for his "amazing review
packets," described as "the best TA I've had."(Fall '92)
